FWIW, I wound a single coil replacement for one of my Nautilus heads yesterday and it vaped pretty well, but needs some customization. It had a tendency to wick slowly at first and lean out and that was probably due to insufficient cotton in the coil or poor contact with the feeder wick in the head and needing more time to saturate. Inserting the coil was as easy as rebuilding a Kanger. If you wanted to do dual coils, there are two sets of slots in the fiber tube that the coils and wicks fit into at right angles to each other. I personally don't see a need for dual coils if a single micro coil is used and engineered properly. It's going to take a little trial and error to get the right feel for creating cotton wicking material in the right thickness to feed the coil optimally.
RipTripper videos were a great help with the Nautilus rebuild. I don't know it I would have tried it had he not done videos on the single and dual coil replacement that made me realize how easy it was to do.
The coil I wound read 1.5 ohms and had approximately 8 to 10 turns on the 1.8mm spindle. I say approximately because it was the first wind from a spool of 28ga Kanthal and I didn't notice at first that there were kinks in the lead end that was wrapped to secure the wire to the spool. I didn't want kinks in the leads coming off the coil itself. I had to unwrap a few turns from the right side and add on the left to extend that to a point where I could cut it off and have nice straight leads to feed down through the tube to the contact points.
I used an organic cotton wick pulled from organic cotton balls. I twisted it tightly at the ends to make it thread into the coil and it was an easy slip fit. I think it needed to be more snug with greater contact pressure. I'll try it again with more cotton in the coil. As with a new Aspire head, it required some break in time to achieve flavor. Don't give up if it doesn't have great flavor at first. If it produces a good cloud, it will break in and vape satisfactorily. Mine tasted a little metallic until I vaped it for a while. I heated the coil to a red hot glow for about 20 seconds with a micro torch to burn off impurities and anneal and set the wire before inserting in the head.
The Gizmo coil winder is definitely a good tool for coil winding. If you don't have a Hobby Lobby store nearby, Amazon sells it. The Deluxe version has 5 crank rods. The sizes are 18-gauge (1.22mm), 15-gauge (1.83mm), 10-gauge (3.25mm), 8-gauge (4.06mm) and 6-gauge (4.88mm). There's a wide gap between the two smallest and the 3 largest. I find 1.83mm to be a good size for micro coils for Kanger and Aspire heads. Some might call it a nano size. There's probably a need for a couple more rods in the 2.x mm range. It's so easy to wind that a rod could easily be made from copper wire and used for creating custom sized coils. You just need a straight piece of stiff wire with a couple or right angles bent in to make a handle for turning the shaft. A small clothes hanger might be just right.
